Flexible light-guiding pipe

Abstract

A folding means for bag knitting apparatus which is intended to fold inwardly the text-printed side portion of the double-layer material strip to be folded to overcome the problems of the conventional bag knitting apparatus, and comprises a clamping roller set, a folding rod set, a supporting set, and a pressing wheel. The double-layer material strip to be folded is opened and enclose the bottom of the folding rod such that the both side portion is placed between the grooves outside the folding rod and the pressing wheel, therefore the material strip is folded as it moves upward through the grooves outside the folding rod and the pressing wheel.

What is claimed is:  
     
       1. An optical fiber device comprising: 
       a pattern having holes;  
       a first flexible light-guiding pipe comprising a first plurality of optical fibers and a first translucent sleeve enclosing said first plurality of optical fibers;  
       a first flexible supporting metal wire arranged axially within said first sleeve to enable said first flexible light-guiding pipe to adjust light direction thereof manually;  
       a transparent dust-proof cap provided at the light-emitting surface of the end of the first flexible light-guiding pipe;  
       a preparatory space formed between said first light-guiding pipe and said transparent cap for allowance of movement of the first plurality of optical fibers,  
       wherein said transparent cap has a front end provided with a threaded hole and a threaded portion with a lens to adjust focus of emitted light; and  
       a second flexible light-guiding pipe comprising a second plurality of optical fibers and a second translucent sleeve enclosing said second plurality of optical fibers;  
       a second flexible supporting metal wire arranged axially within said second sleeve to enable said second flexible light-guiding pipe to adjust light direction thereof manually,  
       wherein said second plurality of optical fibers are extruded out of said second light-guiding pipe by a length, and the exposed portion of said second plurality of optical fibers form a floriated bent pattern so that the end portion of said second plurality of optical fibers extruded out of said second light-guiding pipe penetrates into said pattern having holes.  
     
     
       2. An optical fiber device comprising: 
       a pattern having holes;  
       a first flexible light-guiding pipe comprising a first plurality of optical fibers and a first opaque sleeve enclosing said first plurality of optical fibers;  
       a first flexible supporting metal wire arranged axially within said first sleeve to enable said first flexible light-guiding pipe to adjust light direction thereof manually;  
       a transparent dust-proof cap provided at the light-emitting surface of the end of the first flexible light-guiding pipe;  
       a preparatory space formed between said first light-guiding pipe and said transparent cap for allowance of movement of the first plurality of optical fibers,  
       wherein said transparent cap has a front end provided with a threaded hole and a threaded portion with a lens to adjust focus of emitted light; and  
       a second flexible light-guiding pipe comprising a second plurality of optical fibers and a second opaque sleeve enclosing said second plurality of optical fibers;  
       a second flexible supporting metal wire arranged axially within said second sleeve to enable said second flexible light-guiding pipe to adjust light direction thereof manually,  
       wherein said second plurality of optical fibers are extruded out of said second light-guiding pipe by a length, and the exposed portion of said second plurality of optical fibers form a floriated bent pattern so that the end portion of said second plurality of optical fibers extruded out of said second light-guiding pipe penetrates into said pattern having holes.
